smtp

Hello all. I am looking if I can use the Proxmox Mail Gateway as an outgoing SMTP service. I have a local network and several servers in different clouds. I have several domains, and I need to send all emails to anyone, but from one relay. BR

We want to implement a mail gateway that is forwarding email to a specific mail host based on the MX record. However, the login credentials should be different (for that same mail host) based on the sender address. The email is sent from an application server via SMTP to the local Proxmox Mail...

Hi, I wanted to ask, I have a website that requires an SMTP server to send emails, what does Proxmox Email Gateway do exactly? Does it connect to an SMTP server or create it? I'm a bit confused

In our setup the email outgoing IP (the Pmg, latest version) is different from the incoming mail IP (which is haproxy, that then has the Pmg as backend). I guess it is not an issue to have two different IPs since so many email server work this way, but we see our outgoing mail failing the...

Dear community! I am currently trying to install Proxmox Mail Gateway behind a load balancer. This is because I have limited availability of public IP addresses and want to combine things. Loadbalancer Public IP (example) 1.2.3.4 Loadbalancer internal IP: 10.0.0.1 PMG: 10.0.0.10 I am using...

[EDIT] SOLVED, BY USING THIS FANTASTIC POST: https://forum.proxmox.com/threads/get-postfix-to-send-notifications-email-externally.59940/ Hey all, new to proxmox, so please forgive me my basic questions. I use proxmox on my home-server, so no professional use here. I have one thing left to...

Hi everyone, Longtime PVE user here! I have used Proxmox since mid 2013 for private use, and just recently deployed a couple of Enterprise ones at various companies. I realized that it would be very neat if I during installation or in the WebUI could provide SMTP credentials (SMTP-host...

Hello, I am running into some issues sending mail and was hoping someone may be able to assist. From what I can tell PMG is sending mail externally exclusively on port 25. I am trying to change it to 587 as my ISP blocks port 25. I have attached an image for your reference. Any assistance would...

Hi I'm trying something with PMG. What I want to accomplish, is that I can sent mails from different hosts in different public networks on the internet via PMG acting as a SMTP relay. The problem is, that these hosts on the internet are in networks with dynamic public IP's. So I can't at these...
